CAUTION
The concept of frame mounted type Crack Saws has been successfully utilized for many years as a practical solution to many types of random crack sawing requirements. The basic concept is proven and well accepted within the associated marketplaces. Use of a Crack Saw requires strenuous work activity. This type of work activity can be considered to be greater in magnitude than that experienced with the use of many other types of both light construction and lawn and garden related equipment. This type of work activity should only be attempted by operators of adequate physical size and stature, mental awareness and physical strength and condition. The body parts most noticeably affected during the planing process are the arms, hands, wrists, shoulders, lower back and legs. The process can also produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body parts. Back related pain can be a side effect of utilizing a Crack Saw. An operator with a chronic back related problem or a history of back and/or other medically related problems should not attempt to utilize the Crack Saw. Use of the Crack Saw may only aggravate this and any other medically related problem. Because of the diverse type of prevailing job applications, job site conditions, operator experience levels and operator physical characteristics, no warranty, guarantee, representation and/or liability is made by the manufacturer as to the absolute correctness or sufficiency of any operational procedure, operational position and/or technique. There is no absolute guarantee that an operator of any given experience level, physical size and/or physical condition will be immune to the possibility of and/or probable physical side effects of the normal use of the Crack Saw. Each potential operator must be made aware of and assume the operational and physical liability described and/or associated with the use of the Crack Saw. Improper use of the Crack Saw can result in property damage and/or personal injury, including death. Each potential operator not willing to assume the operational and physical liability described and/or associated with the use of the Crack Saw, should not operate it. Proper levels of operator experience, skill and common sense are essential for maximizing the safe and efficient operation of the Crack Saw.

RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 10
SAFETY PRECAUTIONS
6) Prolonged use of the CRACK SAW (or other, similar machines) exposes the operator to vibrations which may produce Whitefinger Disease (Raynaud's Phenomenon). This phenomenon reduces the hand's ability to feel and regulate temperature, produces numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis. Antivibration systems do not guarantee that you will not sustain Whitefinger Disease. Therefore, continuous and regular users should closely monitor the condition of their hands and fingers. After each period of use, exercise to restore normal blood circulation. If any of the symptoms appear, seek medical advice immediately.
7) Clothing must be sturdy and snug fitting, but allow complete freedom of movement. Never wear loose fitting jackets, scarves, neckties, jewelry, flared or cuffed pants or anything that could become caught on controls or moving parts. Wear long pants to protect your legs. Protect your hands with heavy duty, nonslip gloves to improve your grip. Good footing is most important when operating the CRACK SAW. Wear sturdy boots with nonslip soles. Steel-toed safety shoes are highly recommended. Keep shoes properly laced. Never wear tennis shoes or other, similar type shoes which afford little or no protection. Wear an approved safety hard hat to protect the operator'(s') head(s) where there is a danger of head injuries. Noise, generated by the operation of the CRACK SAW and the actual process itself, can damage your hearing. Wear approved sound barriers (ear plugs or ear mufflers) to protect your hearing. Continuous and regular operators should have their hearing checked regularly.
8) Visually inspect the Crack Saw, components, tools and accessories for damaged or worn parts. BEFORE each use:
a) Disconnect the engine spark plug wire or power source cable.
b) Clean and remove all accumulated foreign matter from the wheels and determine that each rotates freely.
c) Clean and remove all accumulated foreign matter from inside the main frame area.
d) Inspect the V-belt drive for proper tension, wear and general condition. Replace each component as necessary.
e) Inspect the arbor shaft and diamond blade guard assemblies for excessive wear and structural
integrity. Replace each component as necessary. The arbor shaft rotates at high speed during the specific process and can be subject to high wear rates if the installed diamond blade is not properly maintained and/or replaced at regular service intervals. f) Determine that operator controls work freely, all safety devices are operative and information decals are readable.
g) Check to see that the Crack Saw and all related accessories are in good, mechanical condition BEFORE utilization.
h) Reconnect the spark plug wire or power source cable as applicable
9) Contact appropriate representatives to determine if/where electrical cables, gas lines and other hazardous items are buried under the work surface BEFORE utilization.

Before Starting the Engine
FILLING THE ENGINE CRANKCASE WITH OIL.
Note: The RCC130H Crack Saw is shipped with oil in the engine crankcase. Fuel is drained from the fuel tank and will be marked accordingly by factory personnel.
Tools Required: 1 each, small, clean funnel.
The RCC130H Series Crack Saw comes equipped with a Honda 13 HP gasoline engine. The engine is not normally pre-serviced at the factory (see note above) and will require the addition of oil in the crankcase before being placed in service. Consult the material supplied by the engine manufacturer for the engine that has been ordered with your Crack Saw. Carefully review this material to become familiar with specific operating characteristics, recommendations and service requirements.
1) Determine the location(s) of both the oil filler and oil drain plug(s).
2) Wipe oil, dust and accumulated dirt from the filler plug area.
3) Using the funnel, fill the engine crankcase with a high grade motor oil. Consult the material supplied by the engine manufacturer for proper amount, weight and service classification.
4) Replace the oil filler plug and tighten. Wipe off any excess oil spilled on the engine crankcase and Crack Saw.
5) Do not operate the engine unless proper oil level is maintained as per the material supplied by the engine manufacturer.
FILLING THE RCC130H FUEL TANK.
Tools Required: 1 each, small, clean funnel.
CAUTION
Never mix oil with gasoline. Four cycle engines are not designed to be operated with oil mixed with the gasoline.
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 14
ASSEMBLY INSTRUCTIONS/OPERATIONS
1) Determine the location of the fuel tank filler cap.
2) Carefully clean the filler cap and surrounding area to insure that no dirt or debris falls into the fuel tank. Remove the filler cap.
3) Using the funnel, fill the fuel tank with fresh, clean fuel according to the specifications outlined in the material supplied by the engine manufacturer. Do not overfill the tank or spill any fuel. If the fuel tank incorporates a screen mesh to prevent debris from falling into the tank, do not remove to increase the fill rate. Replace the filler cap. Wipe away any excess spilled fuel.
DANGER
MANY FUELS ARE EXTREMELY FLAMMABLE. DO NOT SMOKE NEAR THE FUEL TANK. DO NOT FILL THE FUEL TANK WITH THE ENGINE RUNNING OR IF IT IS HOT. ALLOW AMPLE TIME BETWEEN EACH REFUELING FOR THE ENGINE TO COOL.
Operation
THEORY OF OPERATION.
The RCC130H Crack Saw operates on the principle of transmitting horsepower through a V-Belt transmission directly to an industry standard, 8 inch diameter, diamond segment blade of various widths.
The crack sawing process is directly controlled by these conditions:
a) The use of a suitable mechanism (diamond blade) of proper design and configuration to penetrate the work surface and remove material while delivering acceptable service life.
b) Sufficient static weight supporting the diamond blade to allow it to effectively penetrate the work surface and remove material.
c) Adequate horsepower capable of rotating the diamond blade at industry recognized speeds against the work surface to deliver acceptable productivity rates.
Since no two materials are exactly alike, no two work surface materials can be sawed by the exact same method. The nature of the sawing process, along with operator experience, skill and common sense, would suggest that efficient and productive crack sawing is a matter of trial and error. Combinations of diamond blade type, condition, and
feed rate are direct factors that will also determine the overall success of the job application.
INFORMATION RELATIVE TO THE USE OF DIAMOND BLADES.
Safety requirements always override performance considerations. Diamond blade technology has made such rapid advances during the past few years that a diamond blade, properly used, on well designed and well maintained equipment, can provide the lowest cost per cut of any of the methods of cutting now in use. But, put that same blade onto a piece of poorly maintained equipment and in the hands of a poorly trained operator and the cost of cutting can virtually put you out of business.
The members of the Saw Manufacturer's Institute have been a significant contributor to the state of the diamond blade art. We hope that some of the knowledge and experience that we have accumulated in our many years in the business can, through this booklet, assist you in keeping your cost down to an absolute minimum.
Of all the problems that confront diamond blade users, blade wear is the most difficult to accurately evaluate. Reporting life performance of identical diamond blade specifications operating under seemingly identical conditions tend to be inconsistent.
Masonry blade operators frequently report blade life in terms of hours, days or weeks. However, these reports neglect to mention type of material being cut, the size of the cuts, and the number of cuts per day. In addition, the amount and the cleanliness of the water and the amount of pressure the operator applies to the cut have an effect on blade life.
Obviously, trying to compare the life of one diamond blade with another, simply on the basis of hours, is analogous to trying to compare a set of tires on one car with an identical set on another car...it is virtually impossible. There are just too many variables...the weight of the car, the types of roads driven on, the condition of the car...particularly the suspension, the manner in which the operator handles the car, etc. Just as many variables apply to diamond blades.
So, the next time you have reason to compare blade life, keep these variables in mind. Some of the problems arising from these variables can be quickly identified, and possibly corrected"...

IMPROPER USE OF A DIAMOND BLADE WITH THE CRACK SAW CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
DANGER
PROPER OPERATIONAL USE OF A DIAMOND BLADE THAT DOES NOT MEET INDUSTRY SPECIFICATIONS AND/OR SAFETY STANDARDS WITH THE CRACK SAW CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
General Information.
1) " Only mature, properly instructed adults should be permitted to operate machinery and tools.
2) Only utilize the blade to cut the material it is designed and intended to cut. Blades intended for masonry material (stone, concrete bricks, blocks) or blades for steel or ductile iron must only be used in those materials. If you need to cut a material other than the ones listed above, you must use a blade that has been designed for that specific material. Use of a blade in the wrong material may involve a considerable safety risk. It may also reduce the life of the blade or damage the blade.
3) Inspect all diamond blades for damage before use.
4) Never use a new or used diamond blade that shows damage such as cracks, missing segments, damage to the arbor hole or by the flange washers, or other appearances not consistent with the appearance of a new blade. These are indications of previous improper use. If you have any doubt about the safety of a blade, contact the Customer Service Department of the blade manufacturer for assistance. If you do not know the name of the blade manufacturer, contact the Customer Service Department of General Equipment Company for assistance. There is no charge for this service.
5) Always check that the two mounting flanges are of the same diameter and that they are clean and flat. The flanges should not have any cracks or show any abnormal wear. Make sure that the arbor bolt or nut is the correct one for the equipment without damage to the threads. Improper or damaged flange washers and/or damaged fasteners can damage the
blade or cause the blade to come loose from its mount. A blade that comes loose can cause serious bodily injury or death to the operator or bystander. If there are any questions regarding the suitability of a specific mounting flange, contact the Customer Service Department for assistance BEFORE utilizing the diamond blade. There is no charge for this service.
6) Always make sure that the arbor hole in the blade matches the one on the equipment. Do not force the blade onto the spindle. Do not use an arbor shaft (spindle) and blade combination of different sizes. Proper fit is achieved when the blade slides onto the arbor without having more than 0.1 mm (0.005 inch) radial play.
7) Always tighten the bolt or nut for the flange washers in accordance with the equipment manufacturer's specifications.
8) Always make sure that the equipment used is in good operating condition in accordance with the manufacturer's specifications. Do not operate the equipment unless the guards are in good condition, in the proper place and secure. If the equipment appears to be missing any fasteners or has any parts that appear loose or worn, do not operate the equipment until the appropriate repairs are performed. Always make sure the blade you intend to use with the equipment meets all the equipment manufacturer's specifications.
9) Do not operate the equipment with other than the recommended blade sizes. This can result in severe blade damage. Contact the machine manufacturer for advice.
10) Make sure that the spindle speed on the machine does not exceed the maximum RPM indicated on the diamond blade. This can result in blade breakage. Check the blade shaft with a tachometer to verify that the equipment's maximum RPM does not exceed the manufacturer's specifications.
11) Blades designed for wet cutting must be cooled by an adequate, continuous water flow to each side of the blade. Lack of enough coolant will cause excessive heat, poor blade performance and possible segment loss.
12) Blades designed for dry cutting may be used without water coolant. However, dry cutting blades can overheat which will result in loss of blade tension and may ruin the blade. The risk is greatest during long continuous cutting. Most overheating problems can be avoided by lifting the blade out of
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 16
ASSEMBLY INSTRUCTIONS/OPERATIONS
the cut and letting it cool by rotating in the air for 15 to 20 seconds after every one minute of cutting.
13) Do not force the tool into the material to be cut. A properly working diamond tool will grind the material without excessive force being applied. If excessive force is needed, it indicates there is damage to the blade to the blade or the wrong blade is being used.
14) Always inspect the diamond blade and the equipment any time you stop during the cut. If you notice any difference in performance as your work progresses, immediately STOP and inspect the equipment and the diamond tool.
15) Do not operate any diamond tool without full knowledge about appropriate cooling of the tool. If a tool is not cooled properly, the blade core can become damaged resulting in the segments coming loose or the blade core (the steel) breaking. This
can result in serious bodily injury or death to the operator or bystander.
16) Do not allow any bystanders in the work area. Never allow anyone to stand in front of a saw that is about to be started or is running.
Standards.
The manufacturing of machinery and grinding wheels and the usage of these products are covered in several OSHA and ANSI standards. The most applicable standard for these products is ANSI B7.1 and B7.5. Copies of these standards can be obtained from the American National Standards Institute, 1430 Broadway, New York, NY 10018.
Personal Safety Equipment.
1) Always wear dust masks (respirators) approved for use in concrete and stone dust.
2) Always wear approved eye protection such as goggles or face shield.
3) Always wear approved hearing protection.
4) Always wear approved head protection.
5) Always wear approved safety footwear.
6) Always wear approved gloves.
Note.
In the manufacturing of all diamond blades different metals are used such as Boron, Copper, Colbalt,
Nickel, Iron, Tungsten, Molybdenum, Tin, etc., as outlined in the Material Safety Data Sheet (MSDS). This product as sold presents no hazard although, during use, small amounts of these metal substances may be released into the dust or slurry generated from the material being cut or ground. Prolonged exposure to excessive amounts of dust and slurry may cause respiratory disease, skin irritation or cancer.
Common Sense.
Almost all accidents are avoidable if you apply caution and common sense. Follow all safety precautions at all times. If you are not sure...simply don't do it. Ask for advice. Used improperly or carelessly any tool is dangerous and may cause severe bodily injury or death. If tools are used with caution, proper techniques and common sense, they will do an excellent job for you"...

OPERATING THE RCC130H CRACK SAW ON THE JOB SITE.
DANGER
THE SAWING PROCESS PRODUCES EXCESSIVE NOISE, VIBRATION AND FLYING DEBRIS. ALL OPERATORS AND WORK PERSONNEL IN THE VICINITY OF THE CRACK SAW MUST WEAR APPROPRIATE SAFETY EYE WEAR AND HEARING PROTECTION DEVICES. OTHER SAFETY APPAREL AND/OR PROCEDURES, DEEMED NECESSARY BY SUPERVISORY PERSONNEL MUST ALSO BE WORN AND/OR PRACTICED BY ALL APPROPRIATE PERSONNEL.
DANGER
EXERCISE EXTREME CAUTION WHEN OPERATING THE CRACK SAW IN THE VICINITY OF DECK INSERTS, PIPES, COLUMNS, OPENINGS, LARGE CRACKS, UTILITY OUTLETS OR ANY OBJECT PROTRUDING FROM THE SURFACE. CONTACT WITH SUCH OBJECTS CAN LEAD TO LOSS OF MACHINE CONTROL, RESULTING IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
DANGER
DO NOT OPERATE A GASOLINE ENGINE IN CLOSED SPACES WITHOUT PROPER VENTILATION. GASOLINE ENGINES PRODUCE CARBON MONOXIDE FUMES. BREATHING CARBON MONOXIDE FUMES CAN RESULT IN
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 21
ASSEMBLY INSTRUCTIONS/OPERATIONS
PROPERTY DAMAGE AND/OR PERSONAL INJURY. EXCESSIVE LEVELS OF CARBON MONOXIDE CAN CAUSE DEATH.
1) The Crack Saw is of a downcut type design as viewed by the operator. The diamond blade is intended to rotate toward the operator to enhance visibility and overall productivity while following a random crack. The down cut action results in a "self propelled" effect toward the operator that substantially enhances machine control and reduces fatigue as long as the diamond blade does not come in direct contact with a protruding obstruction from the floor. Direct contact with such an obstruction can result in rapid and jerky directional movement of the machine. In most operating situations, direct contact with a protruding obstruction from the floor will result in serious damage to the diamond blade. This occurrence may not allow the operator to remain in proper control of the machine.
DANGER
ALWAYS MAINTAIN PROPER CONTROL OF THE CRACK SAW. IF AN OPERATOR LOOSES CONTROL OF THE MACHINE, A "RUNAWAY" CRACK SAW CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY. BECAUSE OF THE UNIQUE OPERATING CHARACTERISTICS OF THE CRACK SAW, THERE IS NO PROVISION FOR THE ELECTRIC MOTOR/ENGINE TO AUTOMATICALLY STOP IF THE OPERATOR FAILS TO MAINTAIN PROPER CONTROL.
DANGER
WHEN OPERATING THE CRACK SAW ON ABOVE GROUND FLOOR LEVELS, EXERCISE EXTREME CAUTION TO PREVENT LOSS OF CONTROL THAT COULD ALLOW THE MACHINE AND/OR OPERATOR TO FALL DOWN TO LOWER LEVELS. SUCH AN OCCURRENCE CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
2) The crack sawing process is not intended to require additional weight to be applied to the machine for the purpose of increasing productivity and/or stability. No provision for attaching weight is made.
DANGER
DO NOT OPERATE THE CRACK SAW WITH ADDITIONAL WEIGHT APPLIED DIRECTLY TO THE MACHINE TO INCREASE PRODUCTIVITY RATES AND/OR MACHINE STABILITY. PROPERTY DAMAGE AND/OR PERSONAL INJURY CAN RESULT. PRODUCTIVITY AND/OR STABILITY RELATED PROBLEMS SHOULD BE DIRECTED TO SPECIFIC MECHANICAL PROBLEMS WITH THE MACHINE, OPERATIONAL PROCEDURES AND/OR SPECIFIC MECHANICAL PROBLEMS ASSOCIATED WITH THE DIAMOND BLADE. CONTACT THE CUSTOMER SERVICE DEPARTMENT FOR ASSISTANCE. THERE IS NO CHARGE FOR THIS SERVICE.
3) The Crack Saw is designed to be pulled toward the operator during normal operation to enhance visibility and overall productivity while the blade follows a random crack.
CAUTION
Operating the Crack Saw by pushing it forward will substantially reduce overall productivity and reduce operator control. The diamond blade will deposit dust and residue materials under the feet of the operator. This configuration will not allow the machine to be utilized with a vacuum system. This occurrence can also reduce operator stability on the work surface and lead to property damage and/or personal injury.
4) Position the Crack Saw over the random crack with the diamond blade directly above and parallel with the crack direction. Align the front casters of the machine parallel with the crack direction to maximize operator control at the start of the sawing process. FIGURE 23.
FIGURE 23
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 22
5) Turn the height adjustment lever clockwise to lower the blade into the crack until the desired sawing depth is achieved. Each full turn of the crank lever will raise/lower the blade approximately 1/16 inch.
6) Following the random crack direction and/or pattern with the blade is accomplished by viewing the blade and crack in the louvered opening in the blade guard. The louvers are intended to provide protection for the operator in the event that a diamond segment becomes separated from the blade blank. Probable causes for such occurrences are discussed in detail in the Troubleshooting section of this manual.
a) The geometric design of the louvered blade guard is intended to provide a high mathematical percentage of protection for the operator in a normal operating position as described in this manual. The mathematical percentage will decrease for operating positions not described in this manual.
b) In the event of diamond segment separation from the blade blank, there is a high mathematical probability that the segment will be thrown forward against the dust pan located under the main frame or directly against the forward (non louvered) section of the blade guard. The manufacturer has conducted extensive testing to substantiate this theory. In actual field tests, diamond segments were purposely separated from the blade blanks through abusive operational techniques. In all field tests, no separated diamond segments made direct contact with the blade guard louvers.
c) In the very low probability that a diamond segment would make direct contact with the blade guard louvers, the geometric design has a high mathematical probability to not allow the segment to penetrate the vertical plane as defined by the location of the louvers. The spaces, angle orientation and number of louvers minimize the mathematical probability that a segment can penetrate the vertical plane, exit the louvers and eventually strike the operator.
d) The geometric configuration of the louvers are designed to allow for adequate and/or proper visibility for the operator during the sawing process. With use, concrete and/or asphalt dust will accumulate at the bottom of the blade guard opening. At regular intervals, this material should be removed to enhance operator visibility during the sawing process.
ASSEMBLY INSTRUCTIONS/OPERATIONS
DANGER
DO NOT MODIFY THE ORIGINAL OPERATING CONFIGURATION FOR THE LOUVERS FOR ANY REASON. MODIFICATIONS TO THE LOUVERS CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
7) Proper operator posture and stance will enhance operational safety and overall productivity. FIGURE 24 depicts a proper operator's position. FIGURE 25 depicts an improper operator's position that can accelerate fatigue, decrease productivity and reduce safety. The downcut orientation of the diamond blade will normally produce a "self-propelled" effect against the operator. This effect is intended to reduce the operator fatigue associated with the operation of the machine and to increase overall productivity.
8) In some operating conditions, it may be necessary for the operator to apply a resisting force (push) against the operator handle to counteract the "self-propelled effect. In some other operating conditions, it may be necessary for the operator to apply a force (pull with) to the operator handle in order to assist the sawing action of the Crack Saw.
FIGURE 24
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 23
FIGURE 25 The amount and direction of forces to apply to the operator handle are governed by, but not necessarily limited to the following factors:
a) Average Random Crack Width.
b) Diamond Blade Saw Width.
c) Sawing Depth.
d) Tensile strength of the material being sawed. e) Matrix material of the diamond blade segments in consideration of the aggregate type, amount and/or hardness contained in the material being sawed. f) Service condition of the diamond blade segments.
g) Operating RPM speed range for the diamond blade.
9)For normal job applications, operate the engine at a maximum, governed speed of 3450 RPM. Consult the material supplied by the engine manufacturer and the Specifications section for specific information. If you have any questions regarding specific job applications, contact the Customer Service Department for information. There is no charge for this service. Additional information can be obtained from the Masonry and Concrete Saw Manufacturers Institute, 30200 Detroit Road, Cleveland, OH 44145-1967.
ASSEMBLY INSTRUCTIONS/OPERATIONS
DANGER
THE CRACK SAW IS DESIGNED FOR THE ENGINE TO OPERATE AT A MAXIMUM, GOVERNED SPEED OF 3450 RPM. THIS ENGINE SPEED AND THE V-BELT REDUCTION SYSTEM ALLOWS THE DIAMOND BLADE TO OPERATE WITHIN THE INDUSTRY ACCEPTED RPM SPEED RANGE. FIELD CHANGES AND/OR ALTERATIONS MADE TO THE FACTORY SET ENGINE SPEED RANGE AND/OR V-BELT PULLEY(S) CAN ALLOW THE DIAMOND BLADE TO OPERATE OUTSIDE THE INDUSTRY ACCEPTED RPM SPEED RANGE. THIS OCCURRENCE CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
10) The wide variety of potential work surface materials along with the corresponding variety of job site environments, make it impossible to develop a standardized operating procedure for the Crack Saw. Use of the Crack Saw will require constant trial and error testing until satisfactory results are achieved. Experience gained over time and common sense will help minimize the amount of necessary testing. Many factors will directly affect the operating parameters and/or techniques utilized for a specialized job application. Some of these factors include:
a) Work surface material yield and tensile values. As a general rule, these values will determine material removal rate per unit of time. Materials with high yield and tensile values will characteristically resist/limit material penetration. For such materials, the accepted procedure is to make a number of multiple passes over the work surface rather than attempt to make a single, deep pass. The net effect is to actually increase productivity: more material removed in less time. Other added benefits to this technique are decreased vibration, less operator fatigue and increased component service life.
b) The width of the random crack in comparison to the required cutting width and depth. For example, if the random crack has an average width of 1/8 inch, productivity rates will be greater with the use of a 1/4 inch wide blade over that delivered by a 1/2 inch wide blade. The same analogy can also be used for the cutting depth. Productivity rates will be greater for a 1/2 inch deep cut than a 1-inch deep cut. Deeper cuts also require additional time for the blade to "clear itself" when following a random crack pattern.
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 24
ASSEMBLY INSTRUCTIONS/OPERATIONS
11) The sawing process on many work surface materials can produce sparks, dust and other foreign particle contamination.
DANGER
SPARKS PRODUCED BY THE ACTION OF THE DIAMOND BLADE AGAINST THE WORK SURFACE (FOR EXAMPLE: STRIKING ANCHOR BOLTS) MAY COME IN CONTACT WITH MATERIALS THAT CAN RESULT IN A FIRE AND/OR EXPLOSION. THIS OCCURRENCE CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
DANGER
THE CREATION OF DUST AND OTHER FOREIGN PARTICLE CONTAMINATION FROM THE OPERATIONAL PROCESS CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY. FOR SUCH OPERATING CONDITIONS, ALWAYS WEAR A NIOSH/MSHA APPROVED DUST/MIST RESPIRATOR. CONSULT APPLICABLE OSHA REGULATIONS FOR SPECIFIC INFORMATION.
12) Dust and other particle contamination can be controlled by the following methods:
a) The Crack Saw is equipped with a 3 inch outside diameter vacuum tube adaptor located at the front of the machine. An industrial type vacuum system can be attached to the Crack Saw to remove/control dust and other particle contamination from the work surface. A hose clamp is sometimes required to properly secure the vacuum hose to the vacuum tube. FIGURE 26.
CAUTION
Use of a vacuum system with the Crack Saw will not totally eliminate or provide 100 per cent dust and other particle contamination removal from the atmosphere and work surface. Secondary dust and other particle contamination removal procedures from the atmosphere and work surface will normally be required.
FIGURE 26
DANGER
ALWAYS UTILIZE A VACUUM SYSTEM TO OPERATE WITHIN THE SPECIFIC JOB SITE REQUIREMENT. DUST MATERIAL CAN MEET CLASS II OR CLASS III SPECIFICATIONS OF THE NATIONAL ELECTRIC CODE® FOR HAZARDOUS LOCATION CLASSIFICATIONS. CONSIDERATION MUST ALSO BE GIVEN TO THE CREATION OF HAZARDOUS TYPE MATERIALS REQUIRING SPECIFIC DISPOSAL PROCEDURES. DETERMINE THAT THE VACUUM SYSTEM IS PROPERLY DESIGNED TO OPERATE WITHIN THESE ATMOSPHERES. CONSULT CURRENT NATIONAL ELECTRIC CODE®, OSHA AND ENVIRONMENTAL PROTECTION AGENCY REGULATIONS FOR SPECIFIC INFORMATION.
b) A water stream directed to the blade can be an effective method of reducing dust effects and increasing service life at the same time. The optional RCCWC Wet Sawing Kit can be installed to direct a continuous stream of water to both sides of the diamond blade. FIGURE 27. The kit includes a standard globe type valve to control water feed rates and is directly coupled to a water hose. Potential negative effects of this procedure is that the water and slurry mixture will require additional time for disposal and proper drying before crack filling work can be initiated. Under specific circumstances, the resulting slurry mixture can also be classified as a hazardous material, requiring proper disposal procedures.
13) The Crack Saw is equipped with a quick change height lever designed to raise the diamond blade clear

ASSEMBLY INSTRUCTIONS/OPERATIONS
of the work surface when deployed to its maximum up position. FIGURE 28.
FIGURE 27
FIGURE 28
The quick-change height lever is intended to provide a fast method to raise the blade for the following reasons:
a) When the sawing process is completed for a random crack, the blade can be quickly raised from the work surface and the machine moved by the operator to another random crack on the job site. Lowering the quick change lever to the full down position will return the diamond blade to the specific depth as originally determined by the height adjustment lever. FIGURE 29. The quick change height lever is intended to produce uniform sawing depths for any specific job application.
FIGURE 29
DANGER
EXERCISE EXTREME CAUTION WHEN MOVING THE CRACK SAW ON THE JOB SITE WITH THE POWER SOURCE RUNNING AND THE QUICK CHANGE HEIGHT LEVER OVER CENTER TO ITS REAR MOST (UP) POSITION. IN THIS OPERATING CONFIGURATION, THE DIAMOND BLADE CAN COME IN DIRECT CONTACT WITH FOREIGN OBJECTS AND THE WORK SURFACE ITSELF. THIS OCCURRENCE CAN SUBSTANTIALLY REDUCE MACHINE CONTROL AND PRODUCE FLYING OBJECTS, RESULTING IN PROPERTY DAMAGE AND/OR PERSONAL INJURY. CAUTION ALL ONLOOKERS REGARDING THE POSSIBILITY OF FLYING OBJECTS.
b) If the sawing process overloads the power source to cause complete stoppage, the diamond blade can be readily raised by the operator to clear the work surface before the power source is restarted.
DANGER
DO NOT START AND/OR RESTART THE POWER SOURCE WITH THE DIAMOND BLADE IN DIRECT CONTACT WITH THE WORK SURFACE. BEFORE STARTING AND/OR RESTARTING THE POWER SOURCE, RAISE THE QUICK CHANGE HEIGHT LEVER OVER CENTER TO ITS REAR MOST (UP) POSITION TO ALLOW THE DIAMOND BLADE TO COMPLETELY CLEAR THE WORK SURFACE. IF THIS ACTION DOES NOT COMPLETELY RAISE THE DIAMOND BLADE FROM THE WORK SURFACE, DETERMINE THAT
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 26
ASSEMBLY INSTRUCTIONS/OPERATIONS
A BLADE OF PROPER DIMENSIONS IS BEING UTILIZED. IF THERE ARE ANY QUESTION REGARDING PROPER BLADE DIMENSIONS FOR USE WITH THE CRACK SAW, CONTACT THE CUSTOMER SERVICE DEPARTMENT FOR SPECIFIC INFORMATION. THERE IS NO CHARGE FOR THIS SERVICE.
DANGER
STARTING AND/OR RESTARTING THE CRACK SAW WITH THE DIAMOND BLADE IN DIRECT CONTACT WITH THE WORK SURFACE CAN SUBSTANTIALLY REDUCE MACHINE CONTROL, RESULTING IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
14) Generally speaking, the majority of random crack patterns follow a predominantly straight line with no more than 20˚ variance from an imaginary center line. FIGURE 30. These random crack patterns are easily sawed to the required widths and depths by the properly described diamond blades.
FIGURE 30
However, there are many instances where the random crack pattern follows perpendicular (90˚) to more obtuse (91˚ to 179˚) angles. FIGURE 31. These angles will generally not allow the Crack Saw to properly follow the resulting patterns without significantly reducing operator control, overall productivity and causing severe damage the diamond blade.
FIGURE 31
These types of patterns can be properly sawed by a multiple step process. A segment of the crack is first sawed by the described process (FIGURE 32) and the machine repositioned by the described procedure to saw the intersecting segment. FIGURE
33. This procedure can be repeated as necessary by the geometry of the specific random crack pattern. Following this procedure is especially important when deep (greater than 1/2 inch) saw cuts are required for proper crack filling methods. By utilizing this operating procedure, intricate random crack patterns can be properly sawed while maximizing operator control, overall productivity and extending blade service life.
FIGURE 32

FIGURE 33
DANGER
IMPROPER SAWING PROCEDURES FOR ANY SPECIFIC RANDOM CRACK CAN SUBSTANTIALLY REDUCE OPERATOR CONTROL, OVERALL PRODUCTIVITY AND CAUSE SEVERE DIAMOND BLADE DAMAGE, RESULTING IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
15) Increased productivity rates can usually be achieved in intricate random crack patterns with the use of a wider diamond blade. FIGURE 34.
FIGURE 34
16) Normal usage of the Crack Saw will allow the build-up and accumulation of work surface materials on interior surfaces. It is highly recommended that both the interior and exterior surfaces be properly cleaned after the completion of each usage.

17) On job applications where the work process creates a considerable amount of loose material, it can become almost impossible to determine proper cutting direction for the blade and the extent of work already accomplished. The problem can be compounded if a vacuum system is not utilized. Loose material should be removed by sweeping or other, appropriate processes and the Crack Saw utilized until conditions again warrant removing the accumulated material.

OPERATIONAL PARAMETERS AND TECHNIQUES FOR THE RCC130H SERIES CRACK SAW.
Basic definitions.
There are very few aspects of the pavement maintenance industry that all members, including contractors, engineers, researchers and government agencies can agree on except the inevitability of cracks forming in all types of pavements. To properly address the crack repair procedures, contractors must have a basic understanding of why crack repair is beneficial, crack types to address and the repair materials and methods available.
A basic understanding of the difference between crack filling and crack sealing and the working knowledge to understand which one is appropriate for a specific job application is essential for any pavement maintenance contractor.
An industry accepted definition of crack filling is the placement of materials into cracks to reduce water intrusion and reinforce the adjacent pavement. Crack sealing is the placement of specialized materials either above or into working cracks to prevent the intrusion of water and incompressibles such as sand, aggregate and dirt.
Why Do It at All?
Crack sealing is used as a first line of defense against the deterioration of pavement because of its inherent benefits:
a) It protects the base and sub-base. A good pavement requires a base and sub-base of high structural integrity. Effective crack sealing procedures eliminate water from entering and weakening these areas. The resulting weakness can result in the loss of structural support, which can then further result in the formation of additional cracks and settling around the crack area.
b) It preserves the pavement adjacent to the cracking. Cracks that are properly cleaned and sealed contain filler materials that firmly adhere to the crack sides during times of both expansion and contraction. Without the addition of these filler materials, the adjacent pavement would have increased exposure to the elements, resulting in increased oxidation of the binder, hardening and secondary cracking along the main crack.
c) It eliminates the damaging effects of incompressibles such as sand, aggregate and dirt. When these materials get into a crack they can restrict crack closure during periods of warm weather. The resulting compressive stresses at the faces can create spalling and loosening. In some highly oxidized pavements these stresses can even create pavement lipping, which is the upheaval of pavements at their transverse cracks.
d) It extends pavement life. Sealing procedures allow the contractor to effectively exert control over the base and sub-base conditions, pavement interference and crack growth, thereby extending the pavement's service life.
Types of Cracks.
There are several basic types of cracks: a) Reflective. This type of crack appears primarily in resurfacing projects, although it can also occur in a new pavement surface. Reflective cracks occur when an existing crack or joint in the underlying pavement structure reflects upward through the surface.
b) Joint. A joint is the edge of the individual paving pass made during construction. Such construction joints usually have a lower density than the remaining material. When the placed mats do not bond properly (for any number of reasons), joint cracks can appear.
c) Slippage. Slippage cracks are usually crescent shaped and are created by heavy traffic that is either stopping, turning or climbing a hill. Resultant stresses can cause a bond failure between upper and lower pavement layers. The open end of the U shaped crack always points in the direction of the applied force.
d) Thermal. All pavements expand and contract due to temperature variations. This movement can create cracks. To better allow for movement, pavements need to be constructed with the correct percentage of air voids, which provide for internal stress relief. When the air void percentage is not correct, thermal cracks appear.
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 29
ASSEMBLY INSTRUCTIONS/OPERATIONS
e) Fatigue or alligator. Over time, as a pavement surface ages, it becomes more rigid and has less ability to tolerate vertical load deflections. This occurrence creates a tension and pulling apart in the pavement and results in alligator type cracking. Such cracking can also occur from improper structural capacity and aging. It is generally recommended that alligatored areas be removed and replaced rather than be filled or sealed.
f) Block. This type of crack forms a square pattern, with cracks intersecting at approximate right angles. A common cause of block cracks on asphalt pavements is a lack of traffic, which constantly kneads the pavement and keeps it flexible. Other causes can include excessive air voids in the material.
g) Edge. Edge cracks appear only parallel to and within usually 18 inches of the pavement edge. Cause can include substandard base, lack of shoulder support, inadequate drainage or damage caused by frost.
Equipment and Materials.
Pavement contractors can select from a wide variety of hot or cold applied materials to seal cracks. Unlike cold materials, hot applied sealers are first prepared prior to application. The standard method is a double boiler kettle, which consists of an inner chamber that contains and agitates the sealant material and an outer chamber serving as the heat source.
Heated sealers include rubberized asphalt, low modulus rubberized asphalt, fiberized asphalt and asphalt rubber. Cold applied materials are usually comprised of a self leveling silicone and modified emulsions.
When making a material selection, the pavement contractor must consider many factors. It is critical that the material be placed efficiently and deliver satisfactory performance given the related environmental factors. Other significant factors include preparation and cure times, adhesiveness to the crack sides, cohesiveness in the crack center, resistance to softening and flow, aging and weathering.
Preparation and Application.
The primary purpose of the Crack Saw is to produce a proper configuration in the crack area for the placement of the sealing material. The exact configuration is dependent upon many factors including crack type, pavement downtime and budget restrictions. There are numerous configurations, although all can be grouped into four general classifications:
a) Flush fill. The material is simply dispensed into an existing unsawed crack and the excess struck off.
b) Reservoir. Material is placed only within the confines of a sawed crack, either flush with or slightly below the pavement surface.
c) Overband. Material is placed into and over an unsawed crack and shaped into either a band aid configuration (3 to 5 inches wide and 1/8 inch thick) or given a slight cap.
d) Combination. Material is placed into and over a sawed crack, then is shaped by squeegee into a band centered over the crack reservoir.
The configuration of the random crack ultimately determines the specific type and/or quantity of material utilized in the process.

Maintenance/Service
PREVENTATIVE MAINTENANCE CHECK LIST.
The normal operation of the Crack Saw produces extreme dirt and dust, along with levels of random vibration. Before operating the Crack Saw, the following service list should be accomplished. This list is for reference only and is not intended to be all inclusive. Other subject areas can be added at the discretion of the owner(s) and/or operator(s):
1) Check all fasteners for proper torque values. If a fastener requires retorquing, consult a torque chart for proper value. Properly discard and replace any worn fastener with a factory approved, replacement part.
2) Check the V-belts for wear. Adjust or replace as necessary. Check pulleys for wear and proper alignment. Many loose materials created as a result of operating processes can be extremely abrasive.
3) Keep the Crack Saw clean. Wash the unit after each use. Keep loose materials from accumulating around engine cooling fins. Determine that the interior sections of the frame are free of material build-up. Such a build-up can restrict the operating process and present a potential safety hazard. Clean and remove any material build-up from the Crack Saw after each use.
4) Engine service life can be extended with proper air cleaner maintenance. Consult the material supplied by the engine manufacturer for specific information.
5) Check for proper oil level. Always use clean, high quality engine oil. Change oil as required. Consult the material supplied by the engine manufacturer for specific information.
6) Remove material accumulations from the exterior surfaces of the electric motor. The electric motor is a totally enclosed, fan cooled (TEFC) design. Keep the fan fins clear of material accumulations to enhance air flow over the motor exterior for cooling purposes.

CHECKING V-BELT TENSION AND ALIGNMENT. Application: All Models.
Proper V-belt tension and alignment is essential for smooth transmission of horsepower and extended service life. Improper tension and alignment will accelerate V-belt wear and contribute to decreased productivity. The V-belt is tensioned at the factory with the maximum recommended tension force. Check the belt tension at least two times during the first day of operation as there will normally be a rapid decrease in belt tension until it has been run in. Check the belt tension every eight hours of operation thereafter and maintain tension within the recommended range. The correct operating tension for a V-belt drive is the lowest tension at which it will not slip under peak load conditions.
Tools Required: 1 each, 16 inch minimum length straightedge. 1 each, 10 lbs minimum capacity, tension scale or belt tension tool.
1) Position the Crack Saw on a suitable work bench with the V-belts approximately at waist level.
2) Disconnect the engine spark plug wire.
3) Remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate solvent. Check for signs of wear and damage. Secure in a proper storage area.
CAUTION
Observe all applicable safety precautions for the solvent.
4) Check the belt tension using the spring scale or belt tension tool midway between the engine/motor pulley and the arbor shaft pulley. Belt tension should measure approximately 0.22 inch at 3-1/4 to 4-3/8 lbs. measured force range. FIGURE 35. If tension is within specifications, proceed to Step 5. If tension is not within specifications, refer to INSTALLING A REPLACEMENT V-BELT for specific information.

CAUTION
Observe all applicable safety precautions for the solvent.
3) Remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate solvent. Check for signs of wear and damage. Secure in a proper storage area.
4) Using the 9/16 inch wrenches, loosen the engine/motor mounting capscrews.
5) With the same wrenches, rotate the engine take­up capscrews counterclockwise to loosen the V­belts and allow the engine/electric motor to slide toward the operator handle. FIGURE 37.
6) Remove the worn V-belts. Inspect the engine/electric motor and arbor shaft pulleys for wear and damage. Install the replacement belts, PN BX34 in pairs. The Crack Saw utilizes two V-belts. Always install replacement belts in matched pairs. Never replace just one of the V-belts.
CAUTION
Do not operate the Crack Saw with only one V­belt installed. One V-belt is not capable of transmitting proper horsepower and torque levels to the arbor shaft.
a) Do not install replacement belts if the pulleys have excessively worn grooves. Such pulleys should be replaced to insure proper belt fit. Operating the V­belts in worn pulley grooves will accelerate wear, reduce horsepower and torque levels and significantly reduce component service life.
b) A V-belt should never be forced over a pulley. More belts are broken from this cause than from actual failure in service. c) Keep the belts as clean and free of foreign material as possible. Do not use belt dressing.
FIGURE 37

14) Rotate the arbor shaft by hand to determine the amount of bearing preloading created as a result of the installation process.
Properly installed replacement bearings should rotate without excessive friction, drag and/or "rough spots". If these symptoms occur after assembly, the bearings were improperly supported when pressed into the bearing block. The resulting thrust placed upon the bearing exceeded the static capacity. Bearing operating with these characteristics will deliver minimal service life and be prone to premature failure.

LUBRICATION REQUIREMENTS.
Application: All Models.
Parts Required:
1 each, standard grease gun filled with one of the following: ESSO Beacon 325, Shell Alvania #2, Chevron SRI, or equivalent. 1 each, container of dry film lubricant.
1) Lubricate the rigid caster wheel bearing with a dry film lubricant only. Dry film lubricants dry immediately upon contact. Use sparingly. Excess lubricant will attract the fine grained, powdered materials described in this manual and directly affect bearing service life.
CAUTION
Do not lubricate the rigid caster wheels with any type of grease material. Grease will attract foreign material accumulations that can accelerate bearing wear.
2) The arbor shaft is supported by extra capacity, ball bearings. These bearings are lubricated at the time of manufacture and do not require additional servicing when placing the unit in initial service or during their normal service life. During the first few hours of service, lubrication material may seep from the bearings. This should not be a cause for immediate concern.
3) The swivel wheel casters are sealed to minimize the potential for dust contamination. Lubricate the swivel caster wheels with the grease gun. Use sparingly. Excess lubricant will attract the fine grained, powered materials described in this manual and directly affect bearing service life.
4) Do not apply belt dressing materials to the V-belts for the purpose of minimizing slippage. These products typically attract foreign material accumulations that can accelerate component wear. Excessive V-belt slippage can be eliminated with proper V-belt tension and alignment.

OPERATIONAL PROBLEMS.
DANGER
ALWAYS UTILIZE DIAMOND BLADES IN COMPLIANCE WITH ANSI B7.1, ANSI B7.5 AND/OR LATEST REVISION(S) AND APPLICABLE OSHA REGULATIONS. IMPROPER USE OF DIAMOND BLADES CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
Copies of ANSI B7.1 and B7.5 for review and education purposes can be obtained from the American National Standards Institute, 1430 Broadway, New York, NY, 10018. Copies of the applicable OSHA regulations governing the use of powered equipment and diamond blades can be obtained from your nearest OSHA office.
DIAMOND SEGMENT LOSS
a) The Crack Saw is not being held firmly by the operator, causing the blade to twist or jam in the work surface. Hold the Crack Saw firmly.
b) Overheating due to inadequate supply of coolant (air or water). This is usually accompanied by discolorations which appear on the blade blank in the area of the segment loss. If wet sawing, provide adequate water flow to both sides of the blade. Determine that no water line blockage exists. If dry sawing, periodically allow the blade to run out of the saw cut for up to 20 seconds for every minute of sawing. This will allow the blade to properly cool before resuming sawing operations .
c) The blade blank wears thin as a result of undercutting by abrasive fines generated by the sawing process. The blade blank wears to a knife edge which weakens the blank and causes a segment to separate. If the fines are highly abrasive, wear resistant blanks should be utilized to retard the undercutting phenomenon. Inspect the blades periodically during usage for this occurrence. If wet cutting, allow for ample water to flush the fines out of the saw cut.
d) Improper clamping action by the arbor shaft hub body and hub flange causes the blade to flutter in the cut or fail to support the blade in proper alignment. Always clean foreign material accumulations from the flange surfaces. Replace the flanges if they become bent or deformed with factory approved replacement parts only.
e) The blade can be too hard for the specific material being sawed, causing excessive dullness and segment separation due to impact loads and/or fatigue. This occurrence can also be the direct cause of frictional heat which can melt the brazing filler material that secures the segments to the blade blank. Use a proper blade specification for the material being cut. Match the segment matrix composition to the specific aggregate material being sawed.
f) The blade rotation while sawing is out of round (not concentric), resulting in direct impulse loads being applied to the segments. Replace worn machine components including bearings and arbor shaft. g) Improper blade rotational speed which produces excessive pressure on the segments and subsequent failure of the brazed/welded joint, blade blank or segment itself. Determine that the blade is being operated within the industry recommended RPM speed range. Engine RPM should be checked

TROUBLESHOOTING
periodically with an electronic tachometer to ensure proper operational speed for the blade.
UNEVEN SEGMENT WEAR
a) If wet sawing, insufficient water flow to one side of the blade which effectively reduces the side clearance. Flush the water system. Determine that water is being adequately and equally distributed to both sides of the blade.
b) Worn machine components. Determine that machine components, including bearings, belts and the arbor shaft are not excessively worn and requiring replacement. Determine that the engine runs smoothly to prevent harmonic vibrations which can result in the blade impacting the work surface with impulse type loads.
c) Saw head is misaligned. Periodically check saw head for squareness in both vertical and horizontal planes.
SEGMENT CRACKS
a) Blade matrix composition is too hard for the material being sawed. Utilize a blade with a softer matrix composition.
SHORT BLADE SERVICE LIFE
a) Utilizing the improper blade for sawing a specific material. Avoid the use of a general purpose blade for sawing a single specific material. General purpose blades are intended to saw a wide range of materials. Since it is unlikely that the machine will saw the proper amount of both hard and soft materials proportionately at all times, this type of blade is not the most economical method of sawing. Use a blade with the matrix composition designed specifically for the material and aggregate being sawed.
b) While wet sawing, improper water flow is being delivered to both sides of the blade. Determine that all water hoses are clean and free of any internal blockage. Approximately two to five gallons of water per minute are required to properly cool a blade.
c) Worn machine components. Determine that machine components including bearings, belts and the arbor shaft are not excessively worn and requiring replacement. Determine that the engine runs smoothly to prevent harmonic vibrations which can result in the blade impacting the work surface with impulse type loads.
d) Loss of power, resulting from improper engine RPM speed, electric motor voltage or loose V-belts. See Service section.
BLADE WILL NOT CUT
a) Blade matrix composition is too hard for the material being sawed. Utilize a blade with a softer matrix composition.
b) Blade has become dull, probably as a result a hard matrix composition being utilized to saw a hard material. Dress or sharpen the blade by utilizing it to saw a softer material to expose new diamonds in the segments. If continual dressing is required, it would indicate that the blade matrix composition is too hard for the material being sawed.
c) Failure to initially break in a new blade on a specific material being cut. Allow the blade to sharpen itself on the material to be sawed when first placing it on the Crack Saw. This is the proper method to break in a new blade. Do not force the new blade into a cut as this will generally aggravate the problem.
d) Loss of power, resulting from improper engine RPM speed, electric motor voltage or loose V-belts. See Service section.
e) When dry sawing, the blade becomes dull as a result of overheating, allowing the segment rim to "mushroom" or melt. Discontinue usage and contact the diamond blade manufacturer.
BLADE BLANK WARPAGE
a) The blade blank has been overheated. While wet sawing, improper water flow is being delivered to both sides of the blade. Determine that all water hoses are clean and free of any internal blockage.
b) The blade blank has been overheated. While dry sawing, periodically allow the blade to run out of the cut for up to 20 seconds for every minute sawing. This procedure will allow the blade to cool in a few seconds and allow the sawing process to proceed. If the blade has been warped (dark blue color), it may be damaged beyond repair. A blade in this condition should be discontinued from use immediately and properly discarded.
c) The blade blank has been overheated as a result of spinning on the arbor shaft. Check the arbor shaft, hub body and hub flange for excessive wear and/or damage. Properly tighten the arbor shaft nut.
d) Unequal flange clamping forces. The hub body flange and hub flange must be of the same, identical diameter. Always replace any questionable component with a factory replacement part only.

c) Blade is bent. Contact the blade manufacturer. A blade in this condition should be discontinued from use immediately and properly discarded.
BLADE BLANK DAMAGE
a) Cracks in the blade blank. Contact the blade manufacturer. A blade in this condition should be discontinued from use immediately and properly discarded.
b) Blade blank undercutting. Highly abrasive fines are being generated during the sawing process, resulting in an abrading or wearing away of the blank faster than the diamond segments. Blades manufactured with wear resistant blanks can be specified from many manufacturers. Wear resistant blanks may not be the proper solution to the problem. Any blade experiencing this type of wear problem should be carefully inspected in shorter intervals to determine proper structural integrity.
BLADE NOT ROTATING WITH PROPER CONCENTRICITY
a) Worn machine components. Determine that machine components including bearings, belts and the arbor shaft are not excessively worn and requiring replacement. Determine that the engine runs smoothly to prevent harmonic vibrations which can result in the blade impacting the work surface with impulse type loads.
b) Blade arbor hole damaged from previous usage. A blade in this condition should be discontinued from use immediately and properly discarded.
c) Blade is spinning on the arbor shaft. Check the arbor shaft, hub body and hub flange for excessive wear and/or damage. Worn, bent or dirty hub body flange and hub flange will not allow the blade to be properly tightened on the arbor shaft. Properly tighten the arbor shaft nut. Replace any questionable component with a factory replacement part only.
d) Blade matrix composition is too hard for the material being sawed. Utilize a blade with a softer matrix composition.
e) Blade is not properly mounted to the Crack Saw. Determine that the blade is mounted to the proper diameter spindle before tightening the arbor shaft nut. Never depend on the drive pin of the arbor hub to actually drive the blade. The drive pin is simply a safety device to prevent the blade from spinning on the arbor shaft should the nut become loose.
Improper lubrication. See LUBRICATION REQUIREMENTS.
UNEVEN SAWING ACTION
Excessive material build-up on the caster wheel face surface. Remove the material.
Excessive caster wheel bearing wear. Replace the caster wheel.
Excessive axle wear. Replace axle.
ACCELERATED V-BELT WEAR
Misaligned and/or improperly tensioned pulleys. Readjust pulleys and V-belt. See Service section.
Worn pulleys. Replace pulleys as required. See INSTALLING A REPLACEMENT V-BELT OR PULLEY.
Improper V-belt. Replace with a name brand BX34 series V-belt. Never replace a single belt. Always replace both V-belts at the same time in matched sets.
ACCELERATED BEARING WEAR AND/OF FAILURE
Misaligned and/or improperly tensioned pulleys. readjust pulleys and V-belts. See Service section.
Bent arbor shaft. Replace arbor shaft.

STORAGE
Storage
Proper procedure for long term storage of the Crack Saw will protect it against the effects of corrosion and damage. If the Crack Saw is not to be operated for a period of 30 days or more, proceed to store as follows:
1) Follow Clean all accumulated foreign material from the Crack Saw utilizing an appropriate safety solvent.
CAUTION
Observe all applicable safety precautions for the solvent.
2) Follow the procedure as outlined in the material supplied by the engine manufacturer describing long term storage for the engine.
3) Check all visible parts for wear, breakage or damage. Order any part not required to make the necessary repair. This will avoid a needless delay when operating the Crack Saw at next use.
4) Apply a dry film lubricant to all exposed metal components to prevent rust.
5) Store the Crack Saw inside. If the Crack Saw must be stored outside, protect it with a suitable covering.
